Motion Tracking Troubles
Help Meeee!!
I’m losing my mind here.
I want to track something that starts offscreen and comes onscreen.
I start at the last frame of the scene and track backwards,..but when it gets to the edge it doesn’t go offscreen.
Someone told me i had to precomp and increase the size.
So I did that, went back and tried ago
It STILL stops at the edge.
I’ve tried every combination of Extrapolate at 70%,80% & 90%
I’ve tried it with Subpixel positioning on and off
I’ve tried it with Adapt feature on every frame on and off.
I also tried tracking RGB AND Luminance.
Its really starting to wind me up now, I know it should be simple to sort,..so why can’t I?? 🙁 -

AE tracks pixels, so when they go off screen the tracker gets lost. You have to manually move the track points off screen. It ends up being a lot of trial & error. Check out Aharon Rabinowitz’s new tutorial on tracking with Mocha & be amazed.

You can just move the little plus sign at the middle of the tracker by hand. This is the attach point that all calculations are based on.

Everyone should have bought Mocha when it was
